Our Story
From a garage workshop to powering 50,000+ homes and adventures.
Born from a frustration with lead-acid.
BUKNUWO began in 2018 when our founders — long-time RVers and off-grid enthusiasts — got tired of replacing dead lead-acid batteries every two years. They knew lithium was the answer, but the existing options were expensive, opaque, and didn't last as advertised.
So they started building their own. Working directly with Grade A LiFePO4 cell manufacturers, partnering with top BMS engineers, and obsessing over every detail of safety, balancing and Bluetooth communication.
Today, BUKNUWO ships to over 30 countries. Our batteries power Class A motorhomes, off-grid cabins, fishing boats, golf carts, and whole-home backup systems. And every single one is backed by our 5-year warranty.
Our promise: smart power, built to last.
